The working principle of Bevel Gear Transmission gap backlash eliminating equipment: referring to Fig. 1, the axis hole of the bevel gear 3 and the biography
Cooperation between moving axis 1 has suitable gap, allows axial direction sliding of the bevel gear 3 along transmission shaft 1.It is installed in bevel gear 3
Before transmission shaft 1, Bevel Gear Transmission gap backlash eliminating equipment is first mounted in the shaft shoulder on transmission shaft 1 and abutting transmission shaft 1
2, then bevel gear 3 is installed on transmission shaft 1 and abuts Bevel Gear Transmission gap backlash eliminating equipment, to complete intersection axial cone
The installation of gear driving pair.At this moment, the first gasket ring 4 and the second gasket ring 5 contact without gap (please referring to Fig. 4, Fig. 8), and two
The force application rod 12 is respectively positioned on the outside (please referring to Fig. 8, Fig. 9) of the first circular conical surface 71 of the first gasket ring 4, and the wheel of bevel gear 3
There is gap between tooth and the gear teeth for engaging bevel gear 13.Referring to Fig. 2, equably rotating two screw rods 10, make to be articulated with
The stabilizer blade 11 of screw rod 10 pushes against the cylindrical surface of transmission shaft 1, and the sliding block 9 along the first guide groove 81 to far from transmission shaft 1
Direction sliding, pulls open the distance between two sliding blocks 9, in this way, the force application rod 12 of two C-shapeds is gradually straightened, and makes two
Force application rod 12 generates elastic force, and under the action of elastic force, the intermediate position of two force application rods 12 is respectively from the first circular conical surface 71
Outside (please referring to Fig. 9) it is mobile (please referring to Fig. 2) to first shaft hole 61, i.e., the intermediate position of two force application rods 12 is respectively along the
One circular conical surface 71 (please refers to figure from the lower (please referring to Fig. 8) of the first circular conical surface 71 to the movement of the eminence of the first circular conical surface 71
10) direction first of the first circular conical surface 71 and the second gasket ring 5 that, the first gasket ring 4 is withstood at the intermediate position of two force application rods 12 pads
On the end face of ring 4, so that the first gasket ring 4 be separated with the second gasket ring 5, make to generate gap between the first gasket ring 4 and the second gasket ring 5
(please referring to Figure 10).The distance between two sliding blocks 9 are opened remoter, and the force application rod 12 of two C-shapeds is drawn more straight, and two
The intermediate position of force application rod 12 is moved to higher position along the first circular conical surface 71 respectively, and the first gasket ring 4 and the second gasket ring 5 are divided
It is more opened from obtaining, the gap between the first gasket ring 4 and the second gasket ring 5 is bigger.Referring to Fig. 1, the first gasket ring 4 and the second gasket ring 5
Disengaging movement will push bevel gear 3 and move along the axial direction towards engagement bevel gear 13 of transmission shaft 1, make the gear teeth of bevel gear 3
It is adjacent to each other with the gear teeth for engaging bevel gear 13, and finally eliminate bevel gear 3 with engage bevel gear 13 engaged transmission gap.
Bevel Gear Transmission gap backlash eliminating equipment the utility model has the advantages that please refer to Fig. 1, Fig. 2, the Bevel Gear Transmission gap disappears gap
For device on transmission shaft 1, self-contained structure clips gap adjusting mechanism between the first gasket ring 4 and the second gasket ring 5.Because of the first pad
Ring 4 and the second gasket ring 5 are sheet, therefore axial dimension is small, and because two sliding blocks, 9, two screw rods 10 of composition gap adjusting mechanism,
Two stabilizer blades, 11, two force application rods 12 are distributed in the sagittal plane of transmission shaft 1 and (please refer to Fig. 2), force application rod 12, screw rod 10
Diameter is all smaller (please referring to Fig. 6), although sliding block 9, stabilizer blade 11 are bigger in the axial size of transmission shaft 1, sliding block 9 is embedded in
In first guide groove 81 of the first gasket ring 4 and stabilizer blade 11 is also hidden in the first guide groove 81 and (please refers to Fig. 2, Fig. 7), so bevel gear
The axial dimension of drive gap backlash eliminating equipment is small, compact-sized.
Referring to Fig. 1, in terms of the structure of Bevel Gear Transmission gap backlash eliminating equipment, mounting means and working principle, bevel gear
Drive gap backlash eliminating equipment does not need that additional structure is arranged in original concurrent aces Bevel Gear Transmission structure, need only be with cone
The series winding of gear 3 is on transmission shaft 1 and is located between the axis hole end face of 3 back cone side of bevel gear and the shaft shoulder 2 of transmission shaft 1
It uses, so Bevel Gear Transmission gap backlash eliminating equipment is versatile.In addition, Fig. 1, Fig. 2 are please referred to, first shaft hole 61 and second
The diameter dimension of axis hole 62 need not form public affairs with the diameter dimension of the axle journal of the dress Bevel Gear Transmission gap backlash eliminating equipment of transmission shaft 1
The basic size of difference cooperation, first shaft hole 61 and the second axis hole 62 is more bigger than the basic size of the axle journal of transmission shaft 1 to be made
With therefore, further expanding the versatility of Bevel Gear Transmission gap backlash eliminating equipment.
Referring to Fig. 2, force application rod 12 is manufactured with elastic material (such as spring steel), when bevel gear 3 with engage bevel gear 13
The gear teeth regenerated because of abrasion engaged transmission gap when, intermediate position meeting under the action of elastic force of two force application rods 12
Further mobile (please referring to Fig. 2) to first shaft hole 61 respectively, i.e., the intermediate positions of two force application rods 12 can further edge respectively
First circular conical surface 71 is mobile (please referring to Figure 10) from lower (please referring to Fig. 8) to the eminence of the first circular conical surface 71, thus can be into one
Step separates the first gasket ring 4 with the second gasket ring 5, and can further push bevel gear 3 along the axial towards engagement bevel gear of transmission shaft 1
13 direction is mobile, and finally eliminate bevel gear 3 with engage that bevel gear 13 regenerates by abrasion engaged transmission gap.
Therefore Bevel Gear Transmission gap of the present invention backlash eliminating equipment can compensate automatically bevel gear 3 with engage bevel gear 13 due to abrasion
The engaged transmission gap regenerated.
As an improvement, please refer to Figure 10, Figure 11, in second gasket ring 5 towards setting on the end face of first gasket ring 4
Have with the second circular conical surface 72 of 62 coaxial line of the second axis hole and is radially provided with two the second guide grooves along the second gasket ring 5
82.In other words, second gasket ring 5 is machined with the second circular conical surface 72 with 62 coaxial line of the second axis hole, along the second pad
